Question

A jar contains 24 marbles, some are green and others are blue. If a marble is drawn at random from the jar, the probability that it is green is. Find the number of blue balls in the jar.

Answer 1

Hey!!

Let the number of blue balls be b and that green balls be g

Then ,


Probability = No. of favourable outcomes / Total no.of outcomes



P (g) = g/24


No.of blue balls = 24-g

Answer 2

hello friend!

total number of balls - 24
let the no. of green balls be  A
so, no. of blue balls will be 24 - A

the probability of getting any marble=x/24

I guess ur question isn't complete..

according to the actual question
x/24 = 2/3
x= 16

∴green marbles = 16
and blue marbles = 24 - 16 = 8

hope it helps!
